Do the white lines in the source comp consist of individual layers with opacity property? If so, put this expression in the opacity property of one layer, copy expression only and paste to all other layers in the main comp. It will copy the opacity of the white shapes based on layer order.
comp("source comp").layer(index).transform.opacity
